Structural Parameters of the M87 Globular Clusters
We derive structural parameters for ∼ 2000 globular clusters in the giant Virgo elliptical M87 using extremely deep Hubble Space Telescope images in F606W (V) and F814W (I) taken with the ACS/WFC. The cluster scale sizes ...
The Globular Cluster System of NGC 5128: Ages, Metallicities, Kinematics, and Structural Parameters
Abstract: We review our recent studies of the globular cluster system of NGC 5128. First, we have obtained low-resolution, high signal-to-noise spectroscopy of 72 globular clusters using Gemini-S/GMOS to obtain the ages, ...
